CY74FCT2541TQCT

Overview

The CY74FCT2541TQCT is an octal line driver and MOS driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting inputs and three-state outputs housed in a QSOP-20 surface-mount package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a high-level output current of -15 mA, a low-level output current of 12 mA, and a static current of 200 nA. Propagation delay is specified at 8 ns at 5 V, with a maximum operating temperature of +85°C.

Feature Summary

• Provides unidirectional signal buffering for eight channels with three-state output control
• Designed for direct interface with TTL-compatible logic systems
• Supports MOS load driving capabilities through dedicated output stages

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Multiplexer transceivers

Procurement Notes

Verify the specific suffix 'TQC' against the manufacturer's official documentation to confirm the exact package variant and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements relevant to your manufacturing region. Cross-reference the datasheet revision date to confirm parameter accuracy before finalizing procurement orders.

Selection Notes

Select this component when an octal buffer with three-state capability is required for bus applications. The FCT series offers CMOS performance with TTL compatibility. Consider the QSOP-20 package constraints and the 8 ns propagation delay relative to system timing requirements. Verify that the 5V supply voltage aligns with the target circuit design.

Part Context

This part belongs to the CY74FCT2541 family of octal buffers and line drivers. It shares functional similarities with other FCT series components but is distinguished by its specific pinout, package type, and drive strength characteristics. The TQC suffix indicates a specific surface-mount packaging configuration offered by Texas Instruments for automated assembly processes.

Replacement Considerations

Check for CY74FCT2541 variants with different suffixes such as CT or AT if alternative packages like SOIC are needed. Verify pin-to-pin compatibility with other octal bus drivers from the same FCT family before substitution.
